Localizing infinity-categories with hypercovers
arXiv:1612.03800
Abstract
Given an -category with a set of weak equivalences which is stable under pullback, we show that the mapping spaces of the corresponding localization can be described as group completions of -categories of spans. Furthermore, we show how these -categories of spans are the mapping objects of an -category, which yields a Segal space model for the localization after a Kan fibrant replacement.
